Reason for Belief

I'm pretty excited about a class I'm leading these days at my church, Antioch. It's a book study, in which we're using as a springboard the first seven chapters of Timothy Keller's book, The Reason for God: Belief in an Age of Skepticism. In each of these chapters, Keller responds to one of the common objections to believing in God (as defined by the Christian scriptures). In the first week, we discussed the charge that Christianity's claims are too exclusive to be true. This coming Sunday, we'll tackle the so-called problem of evil and suffering. I get fired up on this subject, since the Christian understanding is the only one that really does justice to the issue.

The Crux of History

This week, people the world over celebrated the single event that more than any other changed history, changed the world. For folks on every continent and in every nation, the crux or crossroads of history is the incarnation, death, and resurrection of Jesus, the Christ.

It is, of course, impossible to fully separate the incarnation (the coming of God in the flesh), the crucifixion (with all it accomplished and the multitude of theological ramifications), and the resurrection. And while each of these doctrines is central and necessary to the Christian faith, most of us (rightly) focus on the latter--resurrection--as we celebrate this week.

The bodily resurrection of Jesus was the incredible news that spread like wildfire through the first-century Roman Empire. It represented the vindication (on the part of God the Father) of Jesus' earthly teachings and of His claim of being one with the Father. It is what changed a ragtag group of uneducated Jewish outcasts--broken and demoralized by the humiliating execution of their leader--into a bold band of mission-minded evangelists, willing to spread their message of assured hope wherever they went and at whatever cost (including ignomious and excruciating martyrdom). His earliest disciples were quick to recognize that Jesus' bodily resurrection meant--because of His promises to that effect--that they too (and all for whom he died) would likewise be raised.

The evidences for the centrality (in human history) of the death and resurrection of Christ are many and varied. For now, let me just point out that much of our language testifies to that centrality. Words I have used in this short essay--'crux,' 'crossroads'--are used to describe centrality, to designate the heart of a matter. These words, of course, share their etymology--as does the word for horrible pain--'excruciating'--with the word for the method by which Jesus was killed, 'crucifixion.'

"Jesus lives!" The events referred to by those two simple words produced a fundamental, cataclysmic, unalterable change in the world. Two thousand years after those events, the power of the Resurrection of Jesus is still producing astonishing transformation in the lives of people, families, tribes, and nations.

For those first followers of Jesus and for millions of believers since, the events we celebrate this week were life-changing--indeed, world-changing. Whatever else may be going on, we now recognize that we live in a world visited by its creator, a world redeemed by his atoning sacrificial death, and a world in which death has been finally and ultimately conquered.

Creation Care and the Christian

(an Earth Day post from a few years back...)

As Christians, we are called to be true environmentalists. That is, the rational link between the Judeo-Christian worldview and the call to care about and for the planet and its component parts is straightforward and clear.

According to the Scriptures, the universe, the planet Earth, and all of its inhabitants were created by God. Psalm 24 begins this way,
The earth is the Lord's and the fulness thereof, the world and those who dwell therein, for he has founded it upon the seas and established it upon the rivers.
Moreover, God gave man (at the very beginning of human history and again later) dominion over the Earth and all of its other inhabitants. This "dominion mandate" is both descriptive and prescriptive. It accurately describes reality. Human beings, with their reasoning (an important aspect of the "image of God" with which they alone of all creatures are endowed by the Creator), do indeed have greater potential and actual impact on the global and local environment than does any other species. The biblical understanding is that this impact can be for good as well as for harm. (By contrast, some of today's most zealous environmentalists see the effect of humans on our planet as only harmful; they deny our potential for being good stewards or carrying out beneficial husbandry.)

The prescriptive aspect of the dominion mandate says that not only do humans have dominion over the planet but that they should take that dominion seriously. We are expected--and accountable to our Creator--to be good stewards of all that He has created.

While the Bible does not teach extensively on this issue (and is largely silent on the how of good stewardship), we can be certain that followers of the one true God are called by Him to care for the creation with which he has blessed us. And while being Christian does not automatically give one any expertise in environmental science, it nonetheless behooves us to be salt (a preserving influence) in our generation with regard to creation care. This means (among other things) being responsible with our individual and local resources (indeed, I would argue that we should be on the forefront of such responsibility) as well as educating ourselves so that we might offer and support reasonable, well-founded solutions to more widespread environmental issues.

There are at least three reasons that Christians need to be better (than we have been in recent generations) at creation care. The first is simply that we are to obey God in all things, and being good stewards is one of those things he has commanded us. Another is for the sake of the environment itself, for the future generations of humans and other creatures that will need its resources. Many of the decisions our generation faces have greater potential for long-term effects on the future livability of our planet than the decisions of any previous generation. (I am not here denying God's sovereignty over such things, but affirming that that sovereignty involves the free will of the humans he created.) Third, our failure to obey the dominion mandate--the fact that Christians have not maintained a position at the forefront of creation-care issues--represents, for many in our generation, a further barrier to their considering the claims of Christianity.

Stewardship of the Earth

Besides being Good Friday on the Christian calendar, April 22nd is Earth Day (and also the birthday of our oldest, Nathan). So here's an appropriate quote written by another Christian thinker, J.R.R. Tolkien.

In The Return of The King, the wizard Gandalf is talking with Denethor, Steward of Gondor, who is despairing in the face of overwhelming odds arrayed against all that he has loved. (Shortly after this dialogue, Denethor takes his own life.)

I take Gandalf's words here to reflect Tolkien's understanding of what every individual is called to--by God--with respect to our care of creation. It certainly expresses my understanding well. Gandalf said...
...the rule of no realm is mine, neither of Gondor nor any other, great or small. But all worthy things that are in peril as the world now stands, these are my care. And for my part, I shall not wholly fail of my task, though Gondor should perish, if anything passes through this night that can still grow fair or bear fruit and flower again in days to come. For I also am a steward.

A Waste of Space?

The movie Contact was not subtle in expressing its main theme. At least four times in the movie, the question is posed, "Do you think there's any other intelligent life out there?" The unvarying response is, "If not, it sure seems like an awful waste of space." The movie, of course, was adapted from Carl Sagan's novel by the same name, and offered a clear portrayal of his worldview, including the Principle of Mediocrity. Sagan was convinced by the sheer magnitude of the universe that life--and even intelligent life--must be everywhere abundant in it. We live in a culture that easily resonates with Sagan's views, where portrayals of such life are indeed everywhere. (You might prefer the original Star Trek series, but your wife likes The Next Generation, your brother is a Battlestar Gallactica fan, and your kids prefer sci-fi video games, but we can all find common ground somewhere in the Star Wars movie series, right?) But Sagan's conclusions in this regard had little to do with empirical science, and have become outdated by the accumulating evidence.

The second king of ancient Israel, the shepherd and psalmist David, likewise wondered at the immensity of the heavens, even though he could only see about 6,000 stars (the number that can be observed with the naked human eye).
When I consider the heavens, what is man that You [O Lord] are mindful of him?
Indeed, the vastness of the universe presents a challenge to folks of all metaphysical stances today. Mormon doctrine has the faithful populating planets throughout the cosmos. In a similar vein, the last book by the late Henry Morris, a young-Earth creationist, postulated that Christians would be given dominion over other planets in the age to come. These speculations on his part were largely fueled, apparently, by his inability to otherwise explain why there are so many stars if life on Earth was a primary purpose of creation.

As it turns out, however, the number of stars (approximately 100 billion trillion) is one of those many characteristics (along with associated parameters like the mass density of the universe and the relative masses of the neutron and proton) that must be just right for life to exist anywhere at any time in the universe. Given the chemistry and physics of the universe, the vast number of stars that exist are precisely what is required for life. Moreover, when the probabilities of such fine-tuning are considered, it becomes astronomically improbable that even one life-support planet exists (apart from a Designer). The question of the origin and existence of life is a separate, equally difficult problem for the naturalist, but that can wait for another post.

In the meantime, here're a couple of other quotes from scientists studying the fine-tuning of the universe. First, British astronomer Sir Fred Hoyle...
...a superintellect has monkeyed with physics, as well as with chemistry and biology.
Likewise, theoretical physicist Tony Rothman wrote...
The medieval theologian who gazed at the night sky through the eyes of Aristotle and saw angels moving the spheres in harmony has become the modern cosmologist who gazes at the same sky through the eyes of Einstein and sees the hand of God not in angels but in the constants of nature.

Electron to Proton Ratio

How about that for a snappy title? Makes you want to call all your friends into the room to check out this blog post, doesn't it?

In the last post, I began to talk about the anthropic principle, the recognition on the part of astronomers, physicists, and chemists that the universe is made with intelligent life as its goal. Today I want to help you begin to appreciate what proponents of this principle mean when they discuss "fine-tuning." The example I'll give you comes from astronomer Hugh Ross' book, The Creator and the Cosmos.

The number of electrons (in the universe) is equivalent to the number of protons to an accuracy of one part in 10 to the 37th power. If it were not so, galaxies, stars, and planets would never form (because electromagnetic forces would so overwhelm gravitational forces).

So what does one part in 10 to the 37th power look like? Ross asks us to imagine the entire North American continent covered in dimes, and that continent-wide pile of dimes reaching all the way to the moon. Now, consider a million such continent-wide, to-the-moon-high stacks of dimes, and among all those dimes a single one painted red. One part in 10 to the 37th power is like a blind-folded person successfully selecting that one red dime on the first try!

And the ratio of electrons to protons is just one of more than 93 characteristics of the universe (so far documented) that exhibit extreme fine-tuning for life. That's why the evidence for design in the universe has led so many astronomers and physicists to use theological language when discussing their results. Take astronomer George Greenspan, for example...
As we survey all the evidence, the thought insistently arises that some supernatural agency--or, rather, Agency--must be involved. Is it possible that suddenly, without intending to, we have stumbled upon scientific proof of the existence of a Supreme Being? Was it God who stepped in and so providentially crafted the cosmos for our benefit?

Copernican or Anthropic?

The Polish astronomer Copernicus (1473-1543) is generally credited with establishing that the center of the solar system is the sun and not the Earth.* Subsequent astronomical research has shown that our sun is not at the center of our galaxy nor is our galaxy at the center of the universe. Add to this the modern recognition that the universe contains on the order of 100 billion trillion stars, and the result is the idea that the Earth is nothing special, location-wise, ontologically, or in its characteristics. This notion, popularized by the late astronomer Carl Sagan, is often referred to as the "Copernican Principle." This is a misnomer, of course, as Copernicus didn't share Sagan's religious views, and didn't overstate the physical evidence to support an unwarranted metaphysical claim. A better name for this idea--still popular among moderns (especially sci-fi fans who, like Sagan, consider it reasonable to think that the Cosmos is replete with planets hosting intelligent life forms)--is the "principle of mediocrity."

Today, however, anyone affirming the principle of mediocrity would be guilty--as was Sagan in his later years--of committing the fallacy of supressed evidence. During Sagan's lifetime and since, overwhelming evidence contrary to Sagan's view has been accumulating. General relativity has by now become the most rigorously tested theory in all of physics, and its logical product--big bang cosmology--has proved fatal for Sagan's view that "The Cosmos is all there is, or ever was, or ever will be." Moreover, astronomers, chemists, and physicists are continually identifying characteristics of the universe that are extremely fine-tuned to provide for human life. The current understanding--the anthropic principle--has turned the "Copernican" Principle on its head, and we now know (for example) that our sun's place within the galaxy and our galaxy's place within the galaxy cluster are (while not central) exactly what they need to be for life on Earth to be possible. According to astrophysicist Paul Davies...
There is for me powerful evidence that there is something going on behind it all… It seems as though somebody has fine-tuned nature’s numbers to make the Universe… The impression of design is overwhelming.
Stephen Hawking likewise expressed the latest understanding,
It would be very difficult to explain why the universe should have begun in just this way, except as the act of a God who intended to create beings like us.
In days to come, I'll be sharing just a few of the 93+ fine-tuned characteristics of the universe itself (fundamental fine-tuning)and the 154+ characteristics of the galaxy, solar system, and Earth (environmental fine-tuning) that fall within extremely narrow (life-permitting) ranges. If you want to learn more about this yourself, I recommend Hugh Ross' The Creator and the Cosmos, The Privileged Planet by Guillermo Gonzalez and Jay Richards, and the Reasons To Believe website (where updated lists of these characteristics can be found).




*Copernicus' immediate successors, Bruno and Galileo, played important roles in getting this understanding out. Moreover, there is some indication that even Ptolemy recognized ours as a heliocentric system. His system of concentric rings (that is to us moderns Ptolemy's legacy and which brands him as geocentric) may have been his best bet for predicting the locations of the planets given the rather undeveloped geometry of his day.

God of the Gaps

[Besides entering my busiest time of year work-wise, I'm teaching one class at the Kilns and another two classes on the internet. What suffers is my time to write new blog posts. So the following is taken from a discussion thread in my internet class, in which I clarify what I take to be the issue with the God-of-the-gaps charge.]

I guess I have a slightly different take on the God-of-the-gaps issue. As I see it, this is not so much something of which Christians generally (and much less practicing scientists who are Christians) are really guilty. Rather, it is an illegitimate charge made against Christians by naturalists. And when naturalists raise this charge, they are generally guilty of several logical fallacies...

1) They are guilty of creating a straw man. While there may be some who easily claim "because God did it" too early in the search for explanations, this is an extreme position and not the one taken by the vast majority of Christians engaged in scientific discussion. When one addresses only the absurd, extreme articulations of his opponents (setting up a straw man that is easily knocked down) instead of addressing the thoughtful, difficult objections made by more moderate opponents, one is being academically disingenuous and logically fallacious.

2) They are guilty of the ad futurum fallacy. (I actually wanted to make up my own name for a fallacy, the "log-in-your-own-eye fallacy," but will stick with a well-recognized name.) But what I mean is that the naturalist is equally guilty (moreso, actually) of engaging in naturalism-of-the-gaps. The claim is that while we don't currently know the natural explanation, give us 75 years and we will. This is a faulty appeal to the future. In good reasoning, one is expected to find the best explanation for all the currently available evidence, rather than appeal to hypothetical future evidence.

3) More fundamentally, the naturalist is guilty of equivocation, wrongly using two significantly different definitions of the 'gaps' being addressed.

The naturalist likes to identify epistemological gaps (gaps of knowledge), and show that historically such gaps have closed. But the more interesting gaps--and those raised by the old-Earth creationist and the proponent of Intelligent Design--are ontological gaps (gaps of existence or being). The naturalist serves his own cause by conflating these two definitions or by ignoring this crucial distinction.

We could discuss (for example) the gap between the existence of a universe and the non-existence of a universe, or the gap between the Edicarean life forms and those of the Cambrian. These are fundamentally gaps of being, not merely gaps in our knowledge. And while the actual gaps involved are unchanging, the epistemological gaps (as we better understand the breadth and suddenness of the Cambrian explosion) are getting larger, not smaller. Perhaps the best example is that of the origin of life. The gap between non-living chemistry and the simplest life is now understood to be much larger than any evolutionary naturalist ever conceived.

So, it is rather uninteresting to note that we ought not be guilty of appealing to the supernatural prematurely, when there is still every indication that a natural (process) explanation will be found (for whatever phenomenon is being studied). But when we are studying origins* questions (rather than process questions), there is every reason to use abductive reasoning, and explanations that involve a supernatural being can reasonably be offered in such cases. This is especially true since only a theistic worldview logically grounds the assumptions that make science worthwhile (as discussed in another thread).



* Failure to differentiate between empirical (process) research and historical (origins) research also serves the scientific naturalist's cause. Whether this represents mere imprecision/naivete or disingenuity on their part I'm never quite sure.

The Peppered Moth Evidence

From the archives again, the post with which I followed up "Green Toothpicks" about 4 years ago...

[In the last post], I shared about an artificial (and rather poor) illustration of natural selection in action ("Green Toothpicks"). The most famous (and much-cited) example of natural selection in the wild is the changes in coloration of the Peppered Moth, changes that occurred as a result of industrialization in Great Britain. These changes were noticed throughout the 19th and early 20th centuries, as Peppered Moth populations went from being mostly white (with a few melanistic individuals) to mostly dark (with a few light individuals). In the 1950's, Bernard Kettlewell, a British biologist and physician, began a series of experiments that led him to believe that this change could be explained as a result of natural selection. He concluded that the moths were eaten by birds (visually-oriented predators) as they rested on tree trunks during the day. Kettlewell reasoned that before industrialization, light-colored moths were more prevalent because they were better camouflaged on the light-colored (and lichen-covered) tree trunks. But with increasing pollution, tree trunks became darker (and lichens died), light-colored moths were less camouflaged than darker ones, and the phenotype of the population became predominantly that of the dark individuals. This elegant example from the wild remains to this day the classic textbook example of natural selection at work.

Subsequent research has cast a great deal of doubt on this entire scenario. It turns out that Peppered Moths don't normally rest on tree trunks but in the crown of the trees, that researchers (including Kettlewell) released moths by day (even though they are a nocturnal species), that many (not including Kettlewell) in fact pinned dead moths to trunks rather than use live ones in their capture-recapture experiments. In addition, neither the distribution of the various color morphs nor that of the lichens fit the patterns predicted by pollution rates, either during the industrialization or following emission controls (when white moths made a comeback in some regions). The problems unearthed have been so serious that what had been called "Darwin's missing evidence" has been deemed invalid even by evolutionary scientists. (For a summary of these problems, the reader is referred to chapter 7 of Jonathan Wells' Icons of Evolution.) Nonetheless, since evidence for the evolutionary paradigm is so scant, this invalidated tale is still a prominent feature in most modern textbooks (with no mention of its problems).

But again, suppose we ignore (for the sake of argument) the fact that subsequent research has shown that the Kettlewell scenario does not provide the evidence for which Darwinists hope. Let us be generous and grant that perhaps further research will discover a mechanism (consistent with natural selection) that explains the change in Peppered Moths. Then, as evidence for macroevolution, we have the same problem here as we had with the green toothpicks. We have--at the end of the experiment--merely a different frequency of the same phenotypes already present at the beginning. Phillip Johnson has stated the problem well (in Darwin on Trial)...
Why do other people, including experts whose intelligence and intellectual integrity I respect, think that evidence of local population fluctuations confirms the hypothesis that natural selection has the capacity to work engineering marvels, to construct wonders like the eye and the wing? Everyone who studies evolution knows that Kettlewell’s peppered moth experiment is the classic demonstration of the power of natural selection, and that Darwinists had to wait almost a century to see even this modest confirmation of their central doctrine. Everyone who studies the experiment knows that it has nothing to do with the origin of any species, or even any variety, because dark and white moths were present throughout the experiment. Only the ratios of one variety to the other changed. How could intelligent people have been so gullible as to imagine that the Kettlewell experiment in any way supported the ambitious claims of Darwinism?
At least two pitfalls (obstacles to objective truth) can be seen in the Peppered Moth story. First, moth researchers used invalid methods and jumped to wrong conclusions primarily because of an inordinant desire to provide evidence for a popular--but evidentially-impoverished--theory. Second, had their conclusions not been spurious, these same researchers (and their popularizers, including textbook editors still today) have been guilty of failing to see the scalar limitations of their results. Evidence of natural selection working at the level of a species quite simply is irrelevant as evidence for macroevolution.

As a scientist, I only hope that the Peppered Moth may serve as a reminder to avoid these pitfalls long after it has been finally discarded as a significant piece of evidence for Darwinian evolution.

Green Toothpicks

I'm pretty busy these days, catching eagles, writing reports, and doing quite a bit of teaching. So, with little time to blog, I've reached back into the archives for the following, originally posted 4 years ago today. It's called "Green Toothpicks."

I took an undergraduate biology class from Dr. "Mad Dog" Johnson, in which he tried to demonstrate natural selection in action. We went outside to a lush, uncut, well-fertilized portion of the campus lawn, where we strew a known number of toothpicks of different colors--red, yellow, blue, and green. We, the students, then acted as predators--the agents of natural selection--foraging through that patch of lawn, capturing as many toothpicks as we could find. As I recall, we found all of the yellow and red toothpicks, most of the blue ones, and almost none of the green, so well-camouflaged were they among the long blades of springtime grass. The lesson was that natural selection works just so on populations of living things.

There are at least a couple of serious problems with this experiment as an illustration of natural selection at work. If--as is claimed--natural selection acting on genetic variation is the mechanism by which evolutionary advance is made, what we demonstrated would seem to be just the opposite. Our toothpick population began with a much higher genetic diversity than it ended with. The population, which now consists almost entirely of green toothpicks, would seem to be much less able to adapt to a changing environment than when it contained the greater diversity of phenotypes. It has ever since seemed to me that we demonstrated that natural selection has a far greater capacity to tend toward extinction than to adaptation and advance.

Another problem with this illustration is just as important. Let us be unreasonably generous and grant that the resulting population of toothpicks is somehow better prepared to adapt to some future environmental change. That is, let us say--for the sake of argument--that what we witnessed was an instance of microevolution. Microevolution refers to the idea that species (and populations and such) are not static, but change over time in both their phenotype and genotype (their morphology and the genetic basis for their morphology, respectively). That microevolution occurs is a well-accepted, non-controversial idea. Let us say that the population of green toothpicks is a good example of something having undergone microevolution. The claim of neo-Darwinism is that it is this same mechanism--natural selection acting upon genetic variation (mutation)--that accounts for macroevolution. In other words, the diversity of all life is explainable by this sort of natural selection acting over vast time scales.

In the specific case of the toothpick illustration, we are to believe that if we waited long enough (as the toothpicks bred generation after generation) and continued preying on those toothpicks most easily spotted, eventually those toothpicks would give rise to species of dental floss, of toothbrushes, and even, eventually, of electric toothbrushes, all without the input of any sort of intelligence or designer.

That there have existed--over the course of Earth's history--different life forms is readily acknowledged. Macroevolutionary theory, as an explanation for how that record came to be, has yet to be substantiated by any evidence. Rare cases of microevolution have been documented, and then we are asked to make the unreasonable and unsupported extrapolation that such minor changes can be invoked to explain all of the advancing complexity witnessed in the fossil record. For me, Professor Johnson's toothpick demonstration has always served as a reminder of the absurdity of the grander claims of evolutionists.

Headin' to Ohio

Looking forward to a weekend back where I grew up, Cincinnati, Ohio. Especially excited about speaking on various apologetics topics to a group of men at a weekend retreat across the border in Indiana. Science and Christianity, Reliability of the New Testament, Historicity of the Resurrection are among the topics I'll tackle.

Jasper and I will also be able to have some Skyline Chili while we're there, and hope to breakfast on goetta once or twice. When in Rome...

Archaeology and the Bible

It is with great pleasure that I refer my readers to the web site of my friend Mike Caba, who researches and visits sites around the world where evidences that corroborate the Bible can be found. At this web site, you can find a host of archaeological discoveries that verify biblical accounts, from the New Testament all the way back to the time of David. Check it out here.

It was Mike who allowed me to tag along on his recent trip to Greece. Mike is also a professor and Dean of Faculty at Kilns College (where I teach). You can take his course in Archaeology and the Bible, or get him to come and give a lecture on a variety of related topics.

Greek Peregrinations

With my buddy, amateur archaeologist and Kilns College Dean of Faculty, Mike Caba, I spent the first week of the new year wandering around Greece. This beautiful country is, of course, full of wonderful examples of ancient art and architecture, and we explored as much of that as we could in the 4 1/2 days we were there. But Greece is also full of New Testament history, and Mike dragged me all over the country to see first-hand some of the evidences that verify places, people, and dates in the life of the apostle Paul and others. We rode subways, taxis, and buses--as well as walking across Athens several times over--to get to Ancient Corinth, Delphi, Marathon, and Elefsina (home of an ancient mystery religion). From time to time, I'll post a bit more about this whirlwind trip and what we saw. Here's a pic of Mike and me at a rather impressive edifice they call the Parthenon.

Eagle Trapping Season


It's the time of year for trapping Golden Eagles, in this case for affixing a telemetry unit (which will use satellites to acquire information on the bird's hourly location). This adult male is one of many year-round residents in my area (there are at least 10 Golden Eagle territories within 10 miles of our home). The photo below shows a bit of the capture method and conditions.


It's tough work, but hey, someone's got to do it.

Merry Christmas

Let me just take this opportunity to wish a very blessed Christmas to all my readers. Here in Central Oregon, we did have a white Christmas, but purists might point out that no new snow fell. Rather, we're still cold enough to retain the 8 or so inches that fell last weekend.

It was a cozy, comfortable day here, with lots of wonderful homemade gifts. My youngest daughter, Willow, has made a tradition of writing poetry and including it in gifts, and a number of homemade bracelets, necklaces, and hair barrettes were also acquired. Books, of course, and music, were also among the presents.

I'm always fascinated by the number of stores and folks at this time of year that do the "Happy Holiday" thing, not expressing the word 'Christmas' for fear they might offend someone. Statistics show that something like 96% of Americans celebrate Christmas, with 91% of them explicitly acknowledging it as the birth of Jesus. Now, I'm not so naive as to think that all such folk actually stop to pray to Him or to give thanks for the gift of that life (and death) 2000 years ago.

Nonetheless, I take comfort in the undeniable fact (testified to, in part, by the uniquely worldwide celebration of Christmas) that that gift remains the central event of all human history, the one that most radically changed the world for good. I only hope that you, my reader, have experienced the joy that comes from personally knowing that Prince of Peace, and that--through His redeeming Resurrection power--you too are a vehicle of goodwill to all men. Merry Christmas.

Laryngeal Nerve in Giraffes

In the past couple of weeks, I received two requests to address Richard Dawkins' claim that the recurrent laryngeal nerve in the modern giraffe provides proof of evolution. To hear and see this claim, go to this YouTube video. The heart of Dawkins' argument is that the unnecessary length of the giraffe's recurrent laryngeal nerve is an example of an imperfection that is the sort of historical accident that one would expect if there is no intelligent Designer. Here's my response...

Since I don't know you, I can't simply respond to Dawkins' claim without first making sure that you understand the larger picture, which is the bankruptcy of Dawkins' overall view, neo-Darwinian evolution (NDE).

Twenty years from now, no one will seriously be defending the form of evolution in which Dawkins believes. His critics, whether theists or fellow-evolutionists, rightly accuse him of living still in the 19th century. Stephen Jay Gould (the leading paleontologist of the last several decades) said that "neo-Darwinism, as a theoretical paradigm, is effectively dead." Geneticist James Shapiro (like Gould, committed to some form of evolution) last year told a packed auditorium in Chicago that "Richard Dawkins is a man who lives in fantasy."

And the reason Dawkins' pet theory is dead is because there is no evidence supporting it. The fossil record was contrary to Darwin's theory when he proposed it, and years of looking for his predicted transitional intermediates have only made the situation worse (for evolution). The apparent heirarchical look of living things remains intact, despite efforts to turn it into a continuous tree. Every life form that has ever lived appeared in the fossil record fully formed, fully functional, and fully adapted to its time on earth and its role in the ecology into which it was created. Every life form has remained unchanged throughout its tenure in earth's history. The only ancestors of Dawkins' modern giraffe for which there is any evidence are modern parent giraffes.

The only other evidential argument for evolution--similarity among living things--suffers from a number of problems. For one thing, similarity among living things is equally well (or better) explained by the view that there is a single Creator (one who repeatedly uses efficient designs rather than make each living thing according to entirely new plans and with entirely different materials). Thus the evolutionist argument is viciously circular: its starting point--that similarity only arises from common ancestry--is the claim that is at issue, and cannot be assumed in order to prove itself.

There are numerous other modern discoveries that make evolution surpassingly implausible, but which are completely ignored by Dawkins. These include the discovery that the universe did indeed have a recent beginning (13.7 b.y., whereas Darwinism assumed an eternal universe, such that natural selection had a nearly infinite amount of time at its disposal), the vast complexity of even the simplest living cell (greatly increasing the gap between non-living chemistry and first life), the information content of DNA, the fine-tuning of the universe for life on this one planet, etc, etc.

It is therefore in the face of overwhelming contrary evidence that Dawkins offers the 'proof' of evolution in the form of the laryngeal nerve of the giraffe. Really?! Really?!?

This is an example of a class of arguments for evolution that involve identifying seemingly 'bad,' imperfect, or suboptimal designs. This line of reasoning is unconvincing--or even downright refuted--for several reasons.

1) It assumes a God-like understanding of the anatomy in question, an understanding that neither Dawkins nor anyone else possesses. Further research is likely to discover good reasons that the nerve in question does not take a more direct route between the brain and the larynx.

2) In all of the more well-known examples, this form of argumentation has indeed been seen to involve ignorance. For a long time, it was the inverted retina (in the human eye) that was lauded by evolutionists as poorly designed, until further research discovered the elegance of it. ("Oops, let's not use that example any more! Let's try the length of the giraffe's laryngeal nerve.")

3) There will never be empirical proof that such a design does not serve an elegant (albeit yet undiscovered) purpose. That is, this argument can never be more than a "seems-to-me" sort of argument. Good science is generally thought to be more rigorous and empirical than this.

4) Even if it could be proved that such a thing constituted a bad design, it is a non-sequitur to conclude that there was no design involved. There was a period during which the Ford Pinto had a rear-end fuel tank problem, which led to numerous explosions, lawsuits, and recalls. But no one concluded as a result that the Pinto arose naturally. The premise of poor design does not yield the conclusion of no design.

[As an aside, it is the obviously fallacious reasoning so frequently employed by Dawkins (as in this case) that causes even atheist philosophers to be embarrassed by him, his books, and his public appearances.]

5) At the outset, Dawkins begins with an statement that is oxymoronic. He says that evolution "would expect" or "would predict" such an arrangement. This involves a problematic mixing of tenses. Now if evolutionists had at a certain time predicted the discovery of such an arrangement, and that prediction was subsequently borne out, then there might be some scientific validity to such a claim. But that, of course, is not what happened. No, however Dawkins may try to spin it, he is not here documenting the predictive success of his theory but rather claiming after the fact (of discovery) that it was the sort of thing that evolution... what? "could have predicted?" "should have predicted?" "might have, but just never got around to predicting?" I trust you see the problem.

6) Again assuming for the sake of argument that the laryngeal nerve in the giraffe is either a poor design or even undesigned, the argument for evolution (and against a Creator) depends upon our believing that there is NO design in the universe. That is, if Dawkins is right, then not only the giraffe's laryngeal nerve but the giraffe, and not only that but all living things, life itself, Earth, the solar system, the universe, everything is undesigned. Indeed, on Dawkins' worldview, even the Ford Pinto was not truly designed because the engineers working on it were merely carrying out the completely deterministic programming of their evolutionarily-derived brains. And it is at this point that Dawkins' beliefs require far more faith than the contrary belief--the default belief of nearly everyone throughout Western history--that things appear so exquisitely designed because they are in fact designed. It is at this point that Dawkins' worldview is most readily seen as that of the Fool of Psalm 14:1.

I know that Dawkins' 'arguments' can seem well-packaged and present a superficial challenge when first encountered. But neither this nor any other of his alledged evidences for evolution can withstand even a little bit of serious scrutiny.

Atheist Pastors

So, a couple of weeks ago, there was an article (here) about a couple of pastors who, despite having become atheists, remain in ministry because they don't know how else to make a living. Here's a lengthy excerpt from the article, including quotes from the men themselves
..."I spent the majority of my life believing and pursuing this religious faith, Christianity," Jack said. "And to get to this point in my life, I just don't feel like I believe anymore."

"The more I read the Bible, the more questions I had," Jack said. "The more things didn't make sense to me -- what it said -- and the more things didn't add up."

Jack said that 10 years ago, he started to feel his faith slipping away. He grew bothered by inconsistencies regarding the last days of Jesus' life, what he described as the improbability of stories like "Noah's Ark" and by attitudes expressed in the Bible regarding women and their place in the world.

"Reading the Bible is what led me not to believe in God," he said.

He said it was difficult to continue to work in ministry. "I just look at it as a job and do what I'm supposed to do," he said. "I've done it for years."

Adam said his initial doubts about God came as he read the work of the so-called New Atheists -- popular authors like the prominent scientist Richard Dawkins. He said the research was intended to help him defend his faith.

"My thinking was that God is big enough to handle any questions that I can come up with," he said but that did not happen.

"I realized that everything I'd been taught to believe was sort of sheltered," Adam said, "and never really looked at secular teaching or other philosophies. ... I thought, 'Oh my gosh. Am I believing the wrong things? Have I spent my entire life and my career promoting something that is not true?'
Where shall I begin? I guess with the last quote, "everything I'd been taught to believe..." I assume 'Adam' was taught what to believe both during his upbringing in the church and by his subsequent seminary education. It's pretty clear that he wasn't also taught (either at church or at seminary) how to think. Those 'new atheists' whose arguments he found so persuasive trade in logical fallacies, historical inaccuracies, and rhetoric that embarrasses real philosophers, even atheist ones. And it is very likely that Adam was taught a lot of nonsense that has nothing to do with historic Christianity. ('Jack' referred specifically to the 'story of Noah's ark.' Yes, as told by many modern evangelicals, that story is quite absurd, involving as it does a global flood and pairs of every species of animal that has ever lived. But that, of course, is not what the Bible teaches, but only a modern, superficial interpretation of the passage.)

Yes, many of our churches and seminaries are failing us, both by teaching bad hermeneutics and bad theology and by failing to teach people how to think. But there's a more basic problem that surfaces in this article. And it has to do with the nature of Christian belief.

For these men, belief in God and Christianity seems to be a weighing of the evidence, which is (apparently) only slightly tipped either in favor of or against the Christian worldview. These men of the cloth seem to accept the idea that belief in God is a purely academic exercise. In truth, Christianity claims that the Creator has revealed Himself to us throughout the creation, through history, through Scripture and His Son come to Earth, and in personal experience. That is, true believers are not those who merely weigh all the available evidence to see if God's existence is the slightly likelier option. Those of us who are followers of Christ are such because we have encountered--and fallen in love with--our Creator and Redeemer.

To be sure, saving Christian faith is reasonable and based in evidence. The evidence of God's existence, design, and love are all around us, and it is the task of the apologist to point these out. But may God save us from pastors who have never had a personal encounter with the living Lord, and who moreover don't have the critical thinking skills to spot the absurdity of the arguments of the likes of Richard Dawkins.*


*I understand that true followers of Christ can go through periods of doubt, times at which God seems far from them and they question for a period the reality of His presence in their lives. But when such times come upon pastors who have truly experienced a relationship with God, the response is not to carry on in secret but to go on sabbatical, having first honestly shared with and asked for prayer from one's elders and mentors. The cases of 'Jack' and 'Adam' are like those referred to in I John 2:19, "They went out from us, because they were not of us" except that, for reasons purely of self-interest, 'Jack' and 'Adam' have not gone out from us but shamefully remained as leaders of their congregations.
